Title
Surgical treatment of advanced lymphatic filariasis of lower extremity combining vascularized lymph node transfer and excisional procedures
Abstract
© Copyright 2019, Mary Ann Liebert, Inc., publishers. Background: Lymphatic filariasis (LF) in advanced stage is a clinically challenging disability resulting in poor quality of life. In advanced stage of filariasis, medical management is seldom effective and few surgical procedures are beneficial. In this study, we assessed clinical efficacy of a surgical technique combining vascularized lymph node transfer (VLNT) and serial excision for patients affected by advanced LF. Patients and Methods: A total of 17 patients with grades 2 and 3 lower limb lymphedema after three consecutive humanitarian missions in India between 2014 and 2018 underwent excision of excessive soft tissue of leg and supraclavicular lymph node flap transferred to dorsum of foot. Recipient vessels were prepared and microanastomosis was performed. Lymphedema was assessed by measuring leg circumferences at different levels, episodes of infectious lymphangitis, and lymphoscintigraphy. Results: A significant decrease of lower limb circumference measurements at all levels was noted postoperatively. Postoperative lymphoscintigraphy revealed reduced lymph stasis. One patient suffered of a seroma on donor site. Six patients had partial loss of skin graft over the flap at recipient site and it was managed by regrafting. Data analysis observed statistically significant reduction in feeling of heaviness (p < 0.005) and episodes of acute lymphangitis after surgery. Conclusion: Advanced LF of leg is difficult to manage using traditional medical treatment. The combination of VLNT and surgical excision provided a safe and reliable approach to treat this debilitating disease.
